Idea! A child-nagging toothbrush

I love my kids.  I really do.  They can't remember to brush their teeth for anything.  This gave me a lovely idea today.  I should manufacture a toothbrush that starts playing music if it sits still for 24 continuous hours.  The only way to stop the music should be to shake it (i.e. by brushing your teeth) for 30 seconds.

This idea does not appear to be patented.  If you'd like to manufacture it, please send me an email.  I have lots of ideas, and would gladly trade them for a thinking fellowship gig.  Elizabeth.a.Greene@gmail.com
